Some journals have subcategories of reviews that include labels like "opinion" or "perspective". For example, our 2007 paper in Nature Reviews Neuroscience (Hickok, G., & Poeppel, D. (2007). The cortical organization of speech processing Nature Reviews Neuroscience, 8 (5), 393-402 DOI: 10.1038/nrn2113) appeared in the "Perspectives" section, not the "Reviews" section, and was further branded with the dreaded label, OPINION. I find it amusing how some folks use this in their citation of our wo........ Read more »
Yesterday I mentioned that a key aspect of fighting AIDS is staying on the drug regimen. Charles pointed out that this is more difficult than it might seem: the drugs are constant reminder of your condition, and taking them can revive horrible memories.
But how important is it to maintain adherence to the regimen? A 2008 [...]... Read more »

Cells tend to produce unwanted protein aggregates and other molecular refuse slightly faster than they can get rid of it, resulting in a time-dependent accumulation of potentially toxic cellular garbage. This, in turn, can cause an age-dependent loss of cellular viability, which is (in certain contexts) a fair operational definition of aging.
How can cells deal [...]... Read more »

Mobile phones have drastically transformed our lives. Also known as cellular phones or cell phones, these gadgets not only incorporate a phone, as the name suggests, but also a lot of other technologically advanced features. They include a camera, a sound recorder cum music system, a Bluetooth device and many more depending on the model and the maker of the phone. They are called mobile phones since they can be used while on the move.A mobile phone maintains a two way (transmit and receive) comm........ Read more »

There is considerable deliberations on the international policy agreements on each countries’ magnitude of CO2 reductions to avert catastrophic consequences due to climate change. The main indicator for the allocations are based on the percentage reductions in emission rates relative to 1990. This has had a tendency to split international negotiations into developed and developing countries. The difficulty is due to four main factors with respect to each country: population levels, wealth,........ Read more »

Last month, a terrible earthquake raised havoc in Port-au-Prince, Haiti.

If there is one aspect of "complementary and alternative" medicine (CAM) that can puzzle advocates of science-based medicine, it's why, given how nonsensical much of it is given that some of it actually goes against the laws of physics (think homeopathy or distance healing), CAM is so popular. Obviously one reason is that there are conditions for which SBM does not have any "magic bullet" treatments. Diabetes, heart disease, other chronic illnesses, SBM can manage them quite well, but it can't c........ Read more »

A fascinating thing about DNA replication is that the actual process lacks the ability to replicate the very ends of chromosomes. That means chromosomes should get shorter with every round of cell division (DNA replication), but they remain more or less the same length, getting gradually shorter with aging. The natural shortening of chromosomes is [...]... Read more »

After getting over my little moment of rage there, I decided to go ahead and redo the forams while I could still vaguely remember the phylogeny, sort of. So here comes the Tree of Eukaryotes Expansion Pack: Forams!I hope somebody is happy now, after nagging me about the freaking forams for the past two weeks! I know they deserve more space, and I did them an awful injustice by shrinking the entire group to just 'Forams'. Since I still haven't figured out the space problem (should I just shrink e........

The vivid, intrusive visual images that are a hallmark of post-traumatic disorder (PTSD) are based on a separate memory system from intrusive verbal thoughts. That's according to a new study that claims to provide empirical support for psychologist Chris Brewin's dual-representation theory of PTSD.Brewin's theory posits two memory systems, one that's largely sensation-based, inflexible and automatically accessed and another that's more deliberately accessible, containing material that is context........

It is a long-standing argument among religious believers that religiosity were necessary for morality. In a recent Trends in Cognitive Sciences article (requires subscription), Pyysiäinen and Hauser argue that morality can arise and indeed can be found without and before any religious education and thus religion is a by-product of pre-existing cognitive properties of the brain. Indeed, religion is not ubiquitous, as for instance the Hadza's religion has been described as 'minimal', and yet, coo........ Read more »

Cherie Booth was in the news this week for giving a suspended prison sentence to a man who broke another guy's jaw in an assault, apparently on the grounds that he was religious.
